The industrial robot body 1-1 is located in the middle of the feeding frame 1-2, which is convenient for the industrial robot body 1-1 to grab and transfer the incoming materials to the grinding feeding port.

[0034] The grinding unit 2 of the integrated grinding and tableting equipment of this structure is adjacent to the feeding unit 1, wherein the feeding port of the grinder is located at the top, which is used to receive the materials transferred by the robot. Below the feeding port is a circular grinding disc 2-3, and there is a movable grinding ring inside the circular grinding disc 2-3; when the circular grinding disc 2-3 swings, the incoming materials are ground by the grinding ring, and below the grinding disc is a spring support device and a driving device (conventional components or equipment) to support the grinding disc and achieve rapid swinging of the grinding disc.

[0037] The PLC control unit 8 with an operation panel of the integrated grinding and tableting equipment of this structure is installed on the back panel at the rear of the equipment.

[0038] The working principle or structural principle of the integrated grinding and tableting equipment of this structure:

[0039] The sample preparation requires two parts, the empty ring and the raw material.

[0040] (1) Raw materials are manually loaded into the material box 1-3 on the material rack and picked up by the industrial robot body 1-1. Multiple types of raw materials can be placed at one time, and the industrial robot body 1-1 will pick them up one by one according to the order set by the system.

[0041] (2) After the industrial robot body 1-1 grabs the material box 1-3, it moves to the top of the grinding unit 2. The PLC control unit 8 with an operation panel controls the cylinder 2-1 to open the feeding port of the grinding unit 2 and lift the feeding port cover 2-2. The industrial robot body 1-1 dumps the material box 1-3 to complete the feeding. After waiting for the feeding to be completed, the drive motor 2-5 starts to swing, and the grinding ring inside the grinding disc 2-3 shakes back and forth quickly to crush the raw materials inside the grinding disc 2-3 into powder.

[0042] At the same time, the material ring 7 is loaded and an empty material ring is pushed out from the material ring storage bin 5-4 to the loading conveyor belt 5-3, and is transferred to the designated position by the loading conveyor belt 5-3 to wait.

[0043] (3) The material ring clamp 5-1 in the collecting unit 5 moves to the designated position under the driving cylinder 5-2, grabs the empty material ring and places it on the transfer platform 4-1 on the transfer unit 4; the transfer platform 4-1 moves to the designated position of the grinding disc discharge port 2-4, and is driven by the bottom lifting cylinder 5-2 to fit the material ring 7 with the grinding disc discharge port 2-4, waiting for material receiving.

[0044] (4) The powder is blown out of the grinding disc 2-3 by air blowing and sent to the material ring 7 of the grinding disc discharge port 2-4 for collection.

[0045] (5) After the collection is completed, the lifting cylinder 5-2 is released, the material ring 7 is separated from the grinding plate outlet 2-4, and the transfer platform 4-1 moves, driving the material ring 7 to move to the tableting position; the synchronous dust removal system 9, through the dust removal lifting cylinder 6-1, fits the dust removal air outlet with the grinding plate outlet 2-4 to complete the residual dust collection.

[0046] (6) When the material ring 7 reaches the designated position for tableting, a group of hydraulic drive cylinders 3-2 of the tableting unit 3 is started to drive the tableting head 3-1 to squeeze the material ring 7. After a certain period of time, it is released to complete the tableting operation. The transfer platform 4-1 moves the cabinet again to move the material ring 7 to the unloading position;

[0047] When the transfer platform 4-1 reaches the unloading position, the pneumatic clamp 5-1 of the collecting unit 5 grabs the material ring 7 and places it on the unloading conveyor belt 5-5, which is then sent out by the unloading conveyor belt 5-59. The fixed marking system at the end of the belt uses the marking equipment to code the side of the material ring 7, and then slides into the collecting tray 5-6 to complete the collection.

[0048] At the same time, the dust removal downward pressure cylinder 6-2 drives the dust removal cover to move downward, covering the transfer platform 4-1 and absorbing the residual dust on the platform;

[0049] The single process ends.

[0050] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
